An Alias is an email Address too. Spamkiss provides the possibility create Alias addresses. This needs to be done by the administrator. It is possible to create them as real mailbox or simply as a forward to the main mail address.

Can I assign more than one Token to an alias?

No, you can only assign one Token to each alias. If you do not assign a Token to the alias at all, all Tokens defined for the main address will be valid for it too.
